friction calculations for 3pack and 5 pack container cars

[derekmorton]

Hi Team,

I have been doing some pondering about 3 and 5pack container cars

Request for comment 3 & 5 pack friction calculation

3 pack has 8 axles (12 for 3 wagons)
so friction calculation needs to be (8/12)*4 = 2.7 axles

5 pack has 12 axles (20 for 5 wagons)
so friction calculation needs to be (12/20)*4 = 2.4 axles

does everyone agree?
